The one thing I really don't like about Calibre is how it will copy all of my ebooks into its own file organization. There is probably a way to disable this, but that is the default.
Kind of irritating when you have Calibre in a cloud-storage folder and your books are also in the cloud storage, and it uses up your space with duplicates.
